Patent GB-2337564-A (GB)
Title: Pump shaft seal
Inventor: AGNER IVO
IPC: F04C15/00
Filed: 1999-01-27
Abstract: A pump, such as for hydraulic oil, comprises a drive shaft 11 extending into a housing 3 and mounted on a bearing 21 which is lubricated by a leakage flow of the pumped fluid. A U-shaped sealing ring 29 is provided between the drive shaft 11 and a face of the housing 3 surrounding the drive shaft 11, the respective sealing arms 31,33 of the U resting against the drive shaft 11 and the housing 3 under pre-stress and extending in a direction away from the interior of the pump so that the sealing ring 29 acts as a non-return valve, allowing flow of air or lubricating fluid to pass to the exterior of the pump in use due to the pressure prevailing in the interior of the pump, whilst preventing the escape of oil and ingress of air when the pump is stopped which would affect the starting behaviour of the pump. The sealing ring 29 further comprises an annular spring 29, a pair of sealing lips 41a,41b on the inner sealing arm 31, and a reinforcement device 45 in the outer sealing arm 33.
Patent GB-2347411-A (GB)
Title: Sludge composting aerator
Inventor: WALLACE PHILIP
IPC: C05F17/02
Filed: 1999-02-24
Abstract: Hollow tubes are used to improve the aeration of compostable sludges that have insufficient porosity to allow an adequate oxygen supply to reach the whole bulk of the sludge. The hollow tubes contain air when mixed compared with a solid bulking agent, and they also allow increased passage of air through the sludge. The tubes may be used in varying proportions with the compostable sludge depending on its characteristics. However, the proportions used may be much smaller than other bulking agents (for example woodchips) due to the hollow and open-ended structure of the tubes.

Title: Performing multiply-accumulate operations
Inventor: HINDS CHRISTOPHER NEAL
IPC: G06F9/302
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To perform fast multiplying and accumulating matching the IEEE 754-1985 standards by determining a rounded value needed to generate a final multiplying and accumulating result equivalent to individual multiplication instructions in which rounding is embedded and individual addition instructions in which following rounding is embedded. SOLUTION: The processor is equipped with a multiplier 120 which generates an unrounded multiplication result by multiplying two values by each other and further generates 1st data needed to determine rounding. Similarly, the processor is equipped with an adder which generates an unrounded multiplying and accumulating operation result by adding a specific value to the unrounded result and further generates 2nd data needed to determine rounding. The decision logic 150 uses the 1st and 2nd data to determine a rounding value needed to generate the final multiplying and accumulating operation result equivalent to the execution of individual multiplication instructions wherein rounding is incorporated and individual addition instructions wherein following rounding is incorporated.

Title: Producing a carbon film on a substrate
Inventor: WOLFE JOHN CHARLES
IPC: C01B31/02
Filed: 1999-09-29
Abstract: A method for producing a carbon film on a substrate, comprising the steps of (a) depositing a carbon layer of a predetermined thickness onto the substrate e.g. using off-axis sputtering, the carbon layer having predominantly graphitic or amorphous structure, and (b) treating the carbon layer by means of an radio-frequency discharge in a helium atmosphere wherein the substrate is held at a negative dc bias voltage of a preselected value. The thickness of the carbon layer deposited in step a) may be chosen to be not greater than the longitudinal stop range of the helium ions corresponding to the bias voltage used in step b). After producing a first carbon layer of a predetermined thickness, a next carbon layer is likewise produced upon the first carbon layer and the procedure can be repeated until the total thickness of the layers attains a desired final thickness.

The pinion can rotate relative to the plug, which is fixed to the cap, or the plug can rotate with the pinion and relative to the cap. Cap edge 34 engages a door or frame.
Patent GB-2356401-A (GB)
Title: Method for manipulating protein or DNA sequence data
Inventor: ROBERTS GARETH WYN
IPC: G16B30/10
Filed: 1999-11-19
Abstract: The method enables computational analysis and manipulation of sequence data and allows systematic searches to identify portions of sequences coding for key intermolecular regions of specific protein targets. In an example, two amino acid sequences are input (steps 1,2) to an iterative procedure (steps 4-6). A frame size is selected, in terms of a number of sequence elements. The procedure then compares pairs of frames, one from each sequence, to identify intra- and intermolecular regions on the basis of relationships between amino acids according to a coding scheme. The probability of existence of each region within the scheme is evaluated and those regions for which the probability is greater than a threshold are discarded. The procedure outputs the remaining regions.

Title: Extension of X.509 certificates to simultaneously support multiple cryptographic algorithms
Inventor: PETERS MARK E
IPC: G09C1/00
Filed: 1999-12-17
Abstract: A technique permitting an X.509 certificate to simultaneously support more than one cryptographic algorithm. An alterative public key and alternative signature are provided as extensions in the body of the certificate. These extensions define a second (or more) cryptographic algorithm which may be utilized to verify the certificate. These are not authenticated by the primary signature and signature algorithm in the primary cryptographic algorithm. These newly defined extensions are reviewed by a receiving entity if the entity does not support the cryptographic algorithm of the primary signature.

Date Jan. 4, 1996Closure caps with anti-tamper strips (3) are used to visually display initial opening of a container to the public. The possibility of opening such a container without evidence should be prevented as far as possible. The possibility of stretching the anti-tamper strip (3), in order to then manipulate it past the bead on the container mouth, is here countered by an additional security ring (7). This security ring (7) is arranged coaxially to the actual anti-tamper ring (3). It is connected to the anti-tamper ring and mainly surrounds the lower area (5) of said anti-tamper ring. Access to the actual anti-tamper ring is considerably hindered as a result. In a preferred embodiment, the security ring possesses weakened zones (10) that break during manipulation, so that the interference will be visibly displayed to the outside.

IPC: G06F12/06
Filed: 1985-01-23
Abstract: PURPOSE:To operate a memory device normally even if any one of plural bank registers is failed by switching the failed bank register automatically by a stand-by bank register. CONSTITUTION:When any one of the bank registers 20-23 is failed and any one of selecting circuits 30-33 has an error, a common error register 431 holds logic '1' and the output of an OR gate 430 is turned to '1'. Any one of bank register setting signals S0-S3 is outputted to a NAND gate 405 through AND gates 400-403 and a NOR gate 430. The stand-by bank register 24 stores common bank information CD every system clock until the error is detected by error detecting circuits 410-413. When any one of the circuits 410-413 detects the error, the same information as that of the failed register out of the bank registers 20-23 is stored and then the stand-by register 24 continues to operate instead of the failed register out of the registers 20-23.

IPC: G01B7/02
Filed: 1990-01-22
Abstract: PURPOSE: To electronically measure the displacement of an object larger than the displacement measurable with a strain gauge by providing a spiral coil-like conductor which can provide a wide dynamic range. CONSTITUTION: An electronic (R) converter is composed of a pair of insulated copper wires 10 wound around a mandrel 11 having an appropriate size as two one-layer coils. The coils are sunk in a silastic solution contained in a container 12 and the converter is taken out from the container 12 after silastic (R) are hardened 13. Then insulated wires 15 are respectively attached to one of the end sections of the spiral bodies. In addition, heat-shrinkable sleeves 14 are fitted to the end sections of the hardened thyra-sticks 14 by heat shrinkage. Moreover, eyelets, such as eyelets 15, etc., are buried in the end sections of the converter. Because of the sleeves 14, the end sections of the converter become hard ends and, therefore, only the sensitive section of the converter indicated as the section C-C in the figure can be elongated.
